To 'll whom it may concern: I

Be it known that I, HENRY A. ARNOLD, a citizen of the United States, residing at Lake th and State of Wisconsin, have invented a n `w and use'- ful Compost-Spreader,- of which thel following is a specification.

This invention. has relation to 'compost spreaders and it'fconsists in thenovel construction and arrangement of its parts -as hereinafter shown and described. i

The object of thev invention is to provide a spreader such as indicated which is provided with a traveling conveyer mounted upon its bottom and adapted to ,work or force the material toward the rear end of the apparatus. V c

At the 'rear end of the apparatus is mounted a rotatin distributing cylinder and means is provided or rotating said cylinder .in either over or under-cast distributer.

Means of novel arrangement is provided 4for regulating the rate at which the conveyor will move and means 1s also 'provided for throwing the said conveyer and distributor simultaneously Vout of gear. v

A comb or a ron is mounted upon the bot tom of the b`o y of the'spreader and coperates with the distributer in breaking the material and reducing the lumps thereof to be readily ejected from the spreader without increasing the draft or strain upon the draft animals. Said comb or a ron also coperates with the-conveyer for ringing the material into proper position with relation to the s'preader. supplemental lcomb or apron, such as above indicated, may be `emp andwis` preferable as a reinforcing' means for ,the primary comb when exceptionally tough or frozen material. is being operated upon.

The body ,of the spreader is of such design that it will hold a maximum quantity of maspreader may read p unusually 'tough material `as will hereinafter terial in such manner as to deliver the same readily .to .the conveyor 'and while sup orting wheels of usual diameter are emp oyed the body is lowdown andl maybe readily loaded 4without requiring excessive manual pitching of the material. i

v Means is valso ride over frozen and 5.5 appear. w

The spreader consists of the body 1 which is `substantially `bateau-shaped in general The longitudinally disposed beams 2 are located at the upper 'long ed es .of thel said body while the beams 3 are ocated under the beams 2 at the lower long 5 is a detailed secedges of the body. The studs 4, 4 connect the beams 2 and 3 together, the stlids 4. at

the forward end ofthe body 1, being inin clined positions. The bottom `5 is ocated between the' beams 3', 3 vand the sides 6 are Alocated `within the beams 2 and 3 and the studs 4. The bottom 5 at lthe forward end of the body 1 is inclined in alinement with the longitudinal axes of the studs 4 which" makes a bodybf general shape similar to that of a bateau. The bolster 7 is located under the forward extended ends ofthe beam 2 and rests upon the fifth wheel 8 which in turn is mountedupon the axle 9 provided with the hounds 10 and tongue 11. The wheels 12 are .supported by the `axle 9 andthe said wheels are of such 'diameter that their upper sides lie between the .upper and lower edges of the body 1. By reason of the shape of the however, the said wheels may be readily turned laterally',

together with the axle', without interference on the part of the A body.

Also, wheels of large diameter may be emplo ed which reduce to a minimum the 'traction animals for effecting rotation. The operamounted at the forward end of the body 1. The rear portion o'f the' body 1 is mounted vupon theaxle 14 and the traction wheell is journaled upon the said axle.

everage or strain upon the draftI Thesprocketwheel 16 isv also journaled upon the-axle 14. The clutch 17 is mounted upon the hub of the ,traction wheel 15 and rotates.

with the same and may slide vlaterally upon the hub toward and away from the sprocket wheel 16. The sprocket wheel 18 is jour-1 naled at the side of the body 1 in alinem'ent with the sprocket wheel 16. The sprocket wheel .19 is similarly journaled but 1s posiabove the -sprocket wheel The "said 2 7 provided in the frame of the body l.

sprocket-wheels and 21, (when employed) are j ournaled upon the pin 22 which in turn is mounted upon the body 1. The sprocket wheel 20 lies in the same plane with the sprocket wheels 16, 13 and 19, and the sprocket chain 23 passes around the sprocket `wheel 20, engages the sprocket of the wheel move along t 1e said slots 27 without varyingy the distance between the said. shaft and the pin 224. The s rocket wheel 2S is fixed to the shaft 25 and ies in the same plane as a sprocket Wheel 2l. The sprocket chain 29 passes aroundl the wheels21 and 28. The ratchet wheel is fixedjupon the shaft 31 which is also mounted upon the body 1. The lever 32 is ulcrumed at one end to the shaft 31 and is provided at its opposite end with a curved or arcuate ortion 33 mally lies-in the patli of the laterally disposed roller projections 34 mounted upon the side of the sprocket wheel 16. `The pawl 35 is carried by the lever 32 and is adapted to engage the ratchets of the wheels 30. The

pawl 36 is mounted upon the body- 1 and is also adapted to engage the ratchets of' the Wheel 30A A chain or similar flexible element is attached at one end to the lever 32 and passes over a pulley 38 journaled to the side of the body 1' and connects at its oppositev end with a clip 39 which is adjustably connected with the end of the rod 40 by means of the nuts 41 which are screw thread.- ed u-pon the said rod and which receivethe end` of the said clip between them.- An adjustable stop 4211s .mounted upon the-rod 40. The rocker 43 is pivoted -upon the body 1 and is provided with an eye 44 which receives the rod 40 and is located in the extreme end of the path of the stop 42. Thelower end of the rocker 43 connects With the spring actuated rods or bars 45 which in turn are-:operaH tively connected with the clutch .1?, "The forward end of the rod 40is connected with the lpawl 'and ratchet lever 46 which is ful?l crumed to the side of the body 1 in the vicin` ity ofthe operators seat 13s rlhe shaft 31 isjournaled at the rear end of the bottom 5 of the body 1 and is provided at intermediate points with the s rocket wheels 47, the uper-and' lower si( es of which lie above and elow the upper and lower sides of the said bottom 5.V A shaft y48 is journaled in the adjustable bearings 49 which are located at the forwardend of'the bottoinr of the body 1 and under the inclinedfp'ortion of the saidl which nor- .the material as an um body. The shalt 43 is provided with the sprocket wheels 5G which correspond in nunrber with thesprocliet wheels 47 and are in alinement therewithA The chains :31 pass around the sprocket wheels 47 and 5t) :uid

is of a series of springr teeth or strips 53 which are provided at their lower end with theangularly dis posed portions 54. The portion! 54 driven in the bottoni 5 of the body il and the. staples 55 are also driven in the bottom :3 and straddle the teeth 53. The free ends ofthe teeth 53 are disposed toward the spreader 2-1. The teeth 53 are locateiilbetween the chains The supplemental teeth 56 are. located under the teeth 53. The teeth 56 are also disposed toward the spreader' 24 and are preferably mounted upon a cross shaft 5T journaled in the bottom 5 and which may be partially rotated therein.

The operation ofthe spreader is as follows cm lf it is intendedthat the spreader Z4 operate as an over-cast the chain 23 is brought into engagement with the sprockets of the wheel loaded body 1 is moved over the surface of the ground the traction wheel 15 is rotated.

which through the clutch 17 transmits rotary movement to the sprocket wheel 16. As the chain 23 engages the sprockets of the said wheel 16a-t the upper side thereof' the lower portion of the said chain moves toward the sJrocket wheel 16 and the upper portion of t e chain 23 moves toward wheel 20. `hus thc sprocket. wheels .311 :ind 21 are rotated in thev opposite direction to that in which the wheels 15 and lo :irc rotating. Rotary movement is transmitted from the wheel 21 through the chain ltl and sprocket wheel 28 to the spreader 2-1 which rotates in the same direction as the said wheel 21. l/Vhen the parte are arranged :is above described the said spreader operates as an over-cast. the said spreader the slivroclot chain 23 is )assed-from the sprocket whccl 2() undcr thc lower side of the sprocket wheel 16 then bach l to the wheel 2t), over the sprocket wheel 1u :is

'l`hus,:1s

indicated by dotted lines in sie. 1, the wheels lo is operated in one direct ion the sprocket wheels lo and "l1 are rotated in the saine direction as also the spreader 31. When the spreader' 24 rotates in the same direction as that in which the sprocket wheel 16 is rotated the said s )reader operates upon fercast When operating as an under-castthe spreader 24 may move vertically with its shaft 25 in theurcu ate grooves 27 asa guider This permits the a re thc spri'lchet rl`o reverse thc rotation if -L material th-at'it cannot' rend asunder Without' thus each roller projection 34 lifts the curved ed upon the lever and being in engagement lever 46, rod 4() and chain 37. Thus the conat their rear ends which engage- /the clutchv gear. As the material that is brought back toward the s reader24 by the cross slats 52 A'with relation to the lwheel 15 asthe rods 45A 4seam? spreader to ride over any obstruction. in the l kinjur Y to the machinery. As the vsprocket wheel 16 rotates the roller-projections 34ia're brought successively into lateral Y,contact with the curved end 33 of the lever 32 and end of the said lever and the pawl 35mountwith the ratchets of the wheel30, the said wheel and shaft 31 is partially rotated. The ratchet 36 retains the said wheel 30 against reverse rotation. Thus the shaft 31` is ro'- tated by degrees or stages and the conveyer, made up of the chains 51 and slats 52. is moved longitudinallyof thebottom of the bo 'ly-1,the upper portion of the said .conveyer moving toward the .spreader 24. Thus it lis that the slats 52 are swept along the top of the bottom 5l and the material is brought toward, the spreader 24. The movement of the lever 32 may be governed by an operator upon the seat 13 through'the veyer at the bottom of the body 1 may be moved at will at greater orless'degrees as desired. When the lever 46 is' thrown forward as far as possible the curved end33 of thehlever 32 is carried entirelybeyond thel at iizheel 30 and shaft 31 will remain at rest while the wheel 15S-may rotate. At the same time, the stop 42 engages the eye 44 oftherocker 43 and moves the rods 45 longitudi-` nally against the'tension of the 'springs 45. The rods 45 have obliquely `disposed' 4portions,

17 so that the wheel 16, will'beout of gear are moved rearwardly. Thus 'the spreader operating means and the conveyer operating means may be simultaneously thrown out of approaches t e said spreader it rides u upon he spring teeth of the comb 53 and is s ightly .vated above"th e'ibottom 5 when .it comes contact with the pins 26 of the said spreader. Thus should the said pins 26 come in contact Iwith tough lumps or chunks of the material the teeth ofthe comb 53 will give slightly' so that the said teeth 26 may artially rend or tear the said chunks or umps without jarring the machinery or addto the stress upon the draft animal.- The said chunks or lumps will eventually be torn by the teeth 26 to such an extent as to' beiable to ass between the spreader and the bottomsi e of the body 1. As the slats 52 move toward the spreader 24 they ride over the comb 53 and depress the same. The freev end of the said4 comb, however, by reason of its resilienc and inherent tension will remain Generali isposed toward'the spreader 24.- ti'ihen t e said comb 53 is depressed into an of the roller projectionsi34 and thus the almost horizontal position vit comes in contactwith the supplemental comb 56 which is under tension and has a tendency to maintain the free end of the comb 53 toward. th

tspreader 24 even aftera slat 52 has assed a ong for considerable'distance ofthe eng'th ofthe teeth constituting the comb 53. The intensity with which the comb 56 may operate as an assistant or temporary support for the comb53 maybe regulated by turning the shaft 57 so that the said comb 56 may be -moved into a position moreor less inclined. After the shaft 57 is turned into pro er position it is held against rotation by tfi 58 screw threade u on the -ends thereof and which bear against tlie edges of the bottom 5. -Having described my invention what I claim as new and desire to secure byLetters- Patent is:-
